Another character specific trophy. This one must be done with "Young Nura". He's practically a clone of Rikuo Nura. He's unlocked by completing all of the story modes. This can be done in any mode aside from training, however it is highly recommended you do this in local versus with a second controller.
It's strongly recommended you do this with a second controller because Young Nura is another character who has a "counter" move. His is a bit easier than the others, however, because he doesn't harm the opponent when he counters. Simply move towards your second controller and press Down+
and immediately tap
on the second controller to counter. Repeat 100 times and you'll unlock this.
